From the article:
In an open letter released Wednesday, Microsoft executives contend that IBM is trying to influence the standards process to limit choice. It also said that IBM is encouraging governments to mandate a document format that IBM favours.
Microsoft contends that IBM is trying "to force ODF on users through public procurement mandates," which would have a negative effect on customers and the marketplace...
"We see a level of hypocrisy in IBM's activities... They have long called on us to standardise formats, make the IP (intellectual property) freely available to the broader community, and we've done it. Now that that is done, they are putting a lot of resources to block standardisation" of OOXML, Robertson said. "IBM is fundamentally on the wrong side of the industry."
Elaborating the point, Microsoft states that IBM and other parties are banding together to foist the ODF standard on the industry and that this has negative implications on the customers and the industry as a whole.
The leading software company in the world justifies the submission of the letter by stating 'that Microsoft chose to publish the letter to "shine a light" on IBM's activities'.
This questions the entire rationale of ODF and all the efforts that have been made on it by stating we have genuinely made a better standard but we are not being allowed to publish it.
